Hi Simon. At the beginning this year I migrated from ubuntu 12.10+cyrus2.4.16 to centos7+cyrus2.4.17. All it have worked fine, but month and half after migration I start to notice something was going wrong: time to time I see lots of imap-processes, users complain to access to their mboxes, mail delivery problems, squatter holds at bad mbox and etc.I managed to find who faced to the same problem https://github.com/cyrusimap/cyrus-imapd/issues/1599. In my case I caught the bug exactly as described in link above. I decided to look for more new cyrus version for centos7 and found in kolab repository http://obs.kolabsys.com/repositories/Kolab:/16/CentOS_7/x86_64
Also about how to control squatter task via system scheduler CRON or in-build
one - Cyrus EVENS Section. I think it depends on habits and sysadmin style. For
example, I like starting cyrus routine tasks via EVENTS Section in order to
cyrus-master controls its tasks.
